Ken builds views and search indexes. Automatically.
When the couch_db_update event is triggered with an updated event, ken will spawn indexing jobs for view groups and search indexes (one job per view group shard or search index shard). If a deleted event is triggered, all jobs associated with the corresponding database shard will be removed.
Testing for ken expected to be executed from the top level couchdb repo as a part of make check run. The isolated ken test could be ran as rebar eunit apps=ken verbose=1 from the couchdb's root directory.
